OpenSSL CHANGES
_______________
- Changes between 1.0.0c and 1.0.1 [xx XXX xxxx]
+ Changes between 1.0.0e and 1.0.1 [xx XXX xxxx]
+
+ *) Session-handling fixes:
+ - Fix handling of connections that are resuming with a session ID,
+ but also support Session Tickets.
+ - Fix a bug that suppressed issuing of a new ticket if the client
+ presented a ticket with an expired session.
+ - Try to set the ticket lifetime hint to something reasonable.
+ - Make tickets shorter by excluding irrelevant information.
+ - On the client side, don't ignore renewed tickets.
+ [Adam Langley, Bodo Moeller (Google)]
+
+ *) Fix PSK session representation.
+ [Bodo Moeller]
+
+ *) Add RC4-MD5 and AESNI-SHA1 "stitched" implementations.
+
+ This work was sponsored by Intel.
+ [Andy Polyakov]
+
+ *) Add GCM support to TLS library. Some custom code is needed to split
+ the IV between the fixed (from PRF) and explicit (from TLS record)
+ portions. This adds all GCM ciphersuites supported by RFC5288 and
+ RFC5289. Generalise some AES* cipherstrings to inlclude GCM and
+ add a special AESGCM string for GCM only.
+ [Steve Henson]
+
+ *) Expand range of ctrls for AES GCM. Permit setting invocation
+ field on decrypt and retrieval of invocation field only on encrypt.
+ [Steve Henson]
+
+ *) Add HMAC ECC ciphersuites from RFC5289. Include SHA384 PRF support.
+ As required by RFC5289 these ciphersuites cannot be used if for
+ versions of TLS earlier than 1.2.
+ [Steve Henson]
+
+ *) For FIPS capable OpenSSL interpret a NULL default public key method
+ as unset and return the appopriate default but do *not* set the default.
+ This means we can return the appopriate method in applications that
+ swicth between FIPS and non-FIPS modes.
+ [Steve Henson]
+
+ *) Redirect HMAC and CMAC operations to FIPS module in FIPS mode. If an
+ ENGINE is used then we cannot handle that in the FIPS module so we
+ keep original code iff non-FIPS operations are allowed.
+ [Steve Henson]
+
+ *) Add -attime option to openssl verify.
+ [Peter Eckersley <pde@eff.org> and Ben Laurie]
+
+ *) Redirect DSA and DH operations to FIPS module in FIPS mode.
+ [Steve Henson]
+
+ *) Redirect ECDSA and ECDH operations to FIPS module in FIPS mode. Also use
+ FIPS EC methods unconditionally for now.
+ [Steve Henson]
+
+ *) New build option no-ec2m to disable characteristic 2 code.
+ [Steve Henson]
+
+ *) Backport libcrypto audit of return value checking from 1.1.0-dev; not
+ all cases can be covered as some introduce binary incompatibilities.
+ [Steve Henson]
+
+ *) Redirect RSA operations to FIPS module including keygen,
+ encrypt, decrypt, sign and verify. Block use of non FIPS RSA methods.
+ [Steve Henson]
+
+ *) Add similar low level API blocking to ciphers.
+ [Steve Henson]
+
+ *) Low level digest APIs are not approved in FIPS mode: any attempt
+ to use these will cause a fatal error. Applications that *really* want
+ to use them can use the private_* version instead.
+ [Steve Henson]
+
+ *) Redirect cipher operations to FIPS module for FIPS builds.
+ [Steve Henson]
+
+ *) Redirect digest operations to FIPS module for FIPS builds.
+ [Steve Henson]
+
+ *) Update build system to add "fips" flag which will link in fipscanister.o
+ for static and shared library builds embedding a signature if needed.
+ [Steve Henson]
+
+ *) Output TLS supported curves in preference order instead of numerical
+ order. This is currently hardcoded for the highest order curves first.
+ This should be configurable so applications can judge speed vs strength.
+ [Steve Henson]
+
+ *) Add TLS v1.2 server support for client authentication.
+ [Steve Henson]
+
+ *) Add support for FIPS mode in ssl library: disable SSLv3, non-FIPS ciphers
+ and enable MD5.
+ [Steve Henson]
+
+ *) Functions FIPS_mode_set() and FIPS_mode() which call the underlying
+ FIPS modules versions.
+ [Steve Henson]
+
+ *) Add TLS v1.2 client side support for client authentication. Keep cache
+ of handshake records longer as we don't know the hash algorithm to use
+ until after the certificate request message is received.
+ [Steve Henson]
+
+ *) Initial TLS v1.2 client support. Add a default signature algorithms
+ extension including all the algorithms we support. Parse new signature
+ format in client key exchange. Relax some ECC signing restrictions for
+ TLS v1.2 as indicated in RFC5246.
+ [Steve Henson]
+
+ *) Add server support for TLS v1.2 signature algorithms extension. Switch
+ to new signature format when needed using client digest preference.
+ All server ciphersuites should now work correctly in TLS v1.2. No client
+ support yet and no support for client certificates.
+ [Steve Henson]
+
+ *) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch
+ to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based
+ ciphersuites. At present only RSA key exchange ciphersuites work with
+ TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete
+ SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods
+ and version checking.
+ [Steve Henson]
+
+ *) New option OPENSSL_NO_SSL_INTERN. If an application can be compiled
+ with this defined it will not be affected by any changes to ssl internal
+ structures. Add several utility functions to allow openssl application
+ to work with OPENSSL_NO_SSL_INTERN defined.
+ [Steve Henson]
+
+ *) Add SRP support.
+ [Tom Wu <tjw@cs.stanford.edu> and Ben Laurie]
*) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
[Steve Henson]
Add command line options to s_client/s_server.

+ Changes between 1.0.0d and 1.0.0e [xx XXX xxxx]
+
+ *) Fix bug where CRLs with nextUpdate in the past are sometimes accepted
+ by initialising X509_STORE_CTX properly. (CVE-2011-3207)

a DLL.
*) Change 'Configure' script to enable Camellia by default.
